In Situ SORS spectra of Historical Preservation Fluids in Sealed Containers

In situ Spatially Offset Raman Spectra of 46 historic sample measured at the Natural History Museum (London). The Raman spectra were collected using a handheld commercial SORS instrument (Resolve, Agilent Technologies, Oxfordshire, UK) through a historic jar unsing the matlab scrip presented below. In Addition, the calibration dataset made of the different mockup solution is shared in separete dataset. Three different datasets are provided consisting of the following: 1. SORS spectra of the 46 historica samples, pre-processed by external automatic routine (as described in the paper) (NHM-SORS-hystoric-data.csv) 2. SORS spectra o the 20 calibraion mock up soluion used for PCA analysis (CALIBRATION-DATASET-SORS-NHM.csv) 3. MATLAB scritp used to pre-procese the zero and offsed data extracted from Resolve and calculating the SORS spectra (sors-resolve-datascipt.docx)
